Have you adjusted the valves yet? If they're too tight, you could be losing some compression as the engine warms up and the components expand. Worst case is a valve could kiss a piston, so it's best to check them. .010 I .020 E

If the shutdown solenoid is full of crud or the shaft rusted it can drop down a little once it gets hot.
Solution is easy, remove and clean, don't lose any parts, replace the boot if it's rotted out.
Also check that your throttle cable is in good shape and pulling all the way back to the stop when the pedal is floored.
